_Dasypus novemcinctus mexicanus_ Peters, Monatsber. k. preuss.
Akad. Wissensch. Berlin, p. 180, 1864 (name restricted by
Bailey, N. Amer. Fauna, 25:52, October 24, 1905, to the
subspecies occurring at Colima).
_Range._--Probably statewide.
_Specimens examined_, 2; nos. 51392 from TancA-taro and 51964 from
Apatzingan, 1,040 ft.
_Remarks._--The female from TancA-taro is immature as indicated by the
wide-open sutures between the bones of the skull which in over-all
length is only 72.8 mm. The male from TancA-taro is older and the
over-all length of the skull is 98.33 mm. Geographic considerations
alone are responsible for our use of the subspecific name _mexicanus_;
we do not know the morphological features which distinguish
_mexicanus_ from other named subspecies.
